Abstract: 1,005,433. Improving commutation in dynamo-electric machines. ENGLISH ELECTRIC CO. Ltd. Jan. 5, 1962 [Jan. 5, 1961], No. 462/61. Heading H2A. In a commutator-type dynamo-electric machine, ionized gas is removed from the vicinity of the commutator surface by means of ducts connected to gas-exhausting means and provided with inlets adjacent the commutatorengaging surface of each brush of the machine. As shown in Fig. 1, the brush-holders 13 which are carried by arms 14 provide support for air ducts 15 made of an insulating material such as asbestos cement and provided with inlet slots 16 close to the position where the brushes engage the commutator. In a direct-current machine those ducts associated with the positive brushes are connected together through piping to a common air-extracting fan while the ducts associated with the negative brushes are likewise connected to a second fan; alternatively if de-ionizing means is associated with the piping from each duct, a single fan may be used to extract air through all the ducts of the machine. Fig. 4 shows an alternative form of duct system in which fresh air is forced in through duet 41, the ionized air being removed, as before, through duct 15. The extraction of air also removes wear products from and provides cooling for the brushes and commutator. The brushes may be set at an angle to the commutator or staggered circumferentially with respect to others on the same brush arm, Fig. 5 (not shown). The commutator may operate in a gas other than air.

Title: Improvements in or relating to sonic gas analysers
Inventor: MARTIN ALBERT EDWARD
IPC: G01N29/024
Filed: 1956-01-06
Abstract: <PICT:0805544/III/1> The velocity of propagation of sound waves in a gas or vapour of molecular weight M is inversely proportional to M 1/2 and this property is utilized to determine the molecular weight M1 of a sample gas in a tube.  As shown, a tube 2 contains the sample gas and a similar tube 1 contains a datum gas of known molecular weight M2.  Electro-acoustic transmitters 3 and 4 at the left-hand ends of the tubes are energized from a common electrical A.C. source and the outputs from electro-acoustic receivers 5 and 6 at the opposite ends of the tubes are applied through separate amplifiers 10 and 11 to a phase comparator 7 producing a D.C. output proportional to (M1 1/2 -M2 1/2 ) which is combined with a bias voltage of amplitude M2 1/2 from a potentiometer 9 giving a resultant M1 1/2 which is applied to a non-linear moving-iron meter to give a linear indication of the quantity M1.  Alternatively a single tube containing sample gas may be employed, the inputs to the phase comparator comprising (1) the input to a single transmitter and the output from a single receiver spaced therefrom; or (2) the outputs from two spaced receivers receiving sound waves from a single transmitter; in either case the calibration of the meter scale is set initially by adjustment of the bias voltage.  The phase comparator may be of the type which produces a train of pulses each of duration proportional to the phase difference of the A.C. inputs, said pulses being initiated and terminated respectively by two trains of unipolar pulses derived by shaping the A.C. inputs, Fig. 1 (not shown).

Title: X-ray apparatus
IPC: A61B6/10
Filed: 1973-01-05
Abstract: 1394758 X-ray apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Jan 1973 [8 Jan 1972] 738/73 Heading H5R In X-ray apparatus in which a carriage, e.g. for an X-ray tube, is attached to means actuated by a drive unit to move the carriage along a tiltable patient support table having a member measuring its angle of tilt, the attachment means is constructed to initiate a signal switching off the drive unit if it experiences a force exceeding a pre-set value, such as would be produced by collision with the patient, provision being made to compensate for the force arising merely from tilt of the table. As shown, the carriage 12 is movable along the table 1 by a chain 6 which is driven by a motor 4 and is attached to the carriage via an intermediate point 18 of the helical spring 19, 20. The potentiometer 22 on the carriage, with cursor 21 attached to the spring at point 18, provides a signal dependent upon the force acting on the spring point 18, which signal is compensated for the force arising merely from the tilt of the table by a signal indicative of the latter derived from the potentiometer 10, attached to the table, with cursor 11 attached to the table pivot, the two potentiometers being connected to form a Wheatstone bridge circuit (Fig. 3, not shown) the balance of which is disturbed, to provide a switch-off signal, upon movement of spring-point 18 consequent upon a collision. If the carriage movement is controlled by a hand grip 13, variation of the pressure exerted on which controls the acceleration of the carriage, the signal arising from the acceleration of the carriage may be compensated for by coupling the hand grip to the cursors of two additional potentiometers connected in series with potentiometer 22 (Fig. 4, not shown), in which case the switch-off force on the spring is not limited to a value greater than that arising from acceleration of the carriage. In a modified arrangement, Fig. 2, not shown, the carriage is connected to chain 6 at the points 16 and 18, the potentiometer 22 is mounted on the table 1, and the drive motor is freely mounted on the table in a manner permitting tilting, an arm attached to the motor acting as the cursor 21, whereby an unbalance signal for the Wheatstone bridge is produced by a fluctuation in the torque of the drive motor. In an alternative embodiment, Fig. 5, the carriage and its drive mechanism are secured to the shaft 37 which is resiliently mounted at its ends by springs 40 and 41. Switch contacts 43, the position of which is adjusted with the tilt of the table by the lever system 44, 45, are actuated by the projection 42 upon the carriage experiencing an excessive force.
